This would again assume that you can guarantee that the issue is a violation of the vehicle code. The LEO might think differently when he issues the order and not tell you.

To get to the point, what would you consider a good scenario where you would disobey a direct order by an LEO? We are discussing at least somewhat plausible scenarios, not along the lines of "singing and dancing." Also, I am assuming that the order happens after you have withdrawn any consent and have stopped/are done talking.

This is a genuine question since it tends to be a source of a lot of confusion, much like the infinite threads about how to answer "do you have any weapons in the car."

The only way an LEO can stop you in a vehicle is for violation or perceived violation of the vehicle code. However minor. No blinker, light out ect.
